New headphones, help please! had Fostex TH-X00, whats similar?

[aooo35]

Thanks for taking time to help!

I had Fostex TH-X00 headphones bought from Massdrop. (Not working)
Looking for similar sound quality, what would you suggest?
Is it worth buying from Fostex EU or should i go for other brand and headphones with more reasonable price?

Anything from 300 euro to 700 euro, lower the better...

I have a gracedesign m9xx amplifier also for my headphones.
